¹³ I applied my mind to seek and to search out by wisdom all that is done under heaven; it is an unhappy business that God has given to humans to be busy with.^(A)

¹⁰ I have seen the business that God has given to everyone to be busy with.^(A)

¹⁷ And I applied my mind to know wisdom and to know madness and folly. I perceived that this also is but a chasing after wind.^(A)

¹⁶ When I applied my mind to know wisdom and to see the business that is done on earth, how one’s eyes see sleep neither day nor night, ¹⁷ then I saw all the work of God, that no one can find out what is happening under the sun. However much they may toil in seeking, they will not find it out; even though those who are wise claim to know, they cannot find it out.^(A)
